This is zoysia patch in 3 fairway. Zoysia patch is a disease which begins in the fall. Symptoms don't appear until the spring when it's too late to prevent. Preventative treatments are the only option but unfortunately it is very expensive. We treat two holes that have a history of zoysia patch, but treating all 40 acres is cost prohibitive. Every year we see a few patches and log the areas into the plans to treat in the fall. This fall we will probably add another acre to the scope of area to be treated. The symptoms will linger well into the later part of summer.
